Other Features
Other Features Easy to operate with built-in converter; it can control bipolar stepping motor in full, half, 1/4, 1/8, 1/16 stepping modes; output drive can reach 35V, ±2A; suitable for complex micro processor; in microstep, the chopped wave in the module can automatically choose current attenuation model (slow or mixed) ; in mixed attenuation mode, the default setting is rapid decline in a fixed downtime and slow decline in the rest of the downtime. Mixed decline current control solution reduces motor noise, increase accuracy and decrease power consumption. The sync commutation control of rectifier improves power consumption in PWM operation. With built-in circuit protection: hysteretic overheat switch, UVLO and crossover current protection. No special electrifying program needed. QFN (ES) installation: 5mm x 5mm, nominal overall package height: 0.90mm; with exposed cooler. Lead-free packaging (-T) ; uses fog tin plated pin socket.
